A power connector includes an insulative housing, a set of conductive first contacts and a set of conductive second contacts. The insulative housing includes a receiving space defined inwardly from a front surface of the insulative housing and an inner portion extending from a rear wall of the housing and bounded on its sides by the receiving space. The set of conductive first contacts includes first mating contacts and a first soldering contact, the first mating contacts assembled in the inner portion and partly exposed in the receiving space, the first soldering portion assembled into the housing and electrically contacting the first mating contacts. The set of conductive second contacts includes second mating contacts and a second soldering contact, the second mating contacts assembled in the insulative housing and partly exposed in the receiving space, the second soldering contact inserted into the insulative housing and electrically contacting the second mating contacts.
